Zoom is the most widely used video conferencing platform for UK businesses, supporting meetings, webinars, phone systems, and breakout rooms. The free tier allows 40-minute group meetings with up to 100 participants — enough for most team stand-ups and client calls. Pro (£11.99/month per host) removes the time limit. Zoom is GDPR compliant with EU data routing available for UK businesses, and integrates with Slack, Google Calendar, and Outlook.
